system goes to sleep after locking screen and closing lid

[ronso0]

Reproduce:
* open Power Manager
* General > Laptop Lid > switch off display
* System > Sleep mode: suspend, When inactive for: never
* Display > disable all actions
 (state of On/Off switch at the top doesn't matter)
* lock screen (screen turns off)
* close lid
= system goes to sleep

System shouldn't do anyting, the screen is already off after locking it.

Ubuntu Studio 18.04.1 LTS
xfce4 4.12
xfce4-power-manager 1.6.1-0ubuntu1

Adding "HandleLidSwitch=ignore" to /etc/systemd/logind.conf does not help?

When you manually lock the screen with light-locker it will switch to another VT, and therefore not let xfce4-power-manager handle the lid close event anymore (systemd is in charge now).

"HandleLidSwitch=ignore" in /etc/systemd/logind.conf solves the issue.
Tried that before, but appearantly a restart was necessary.

FYI: Directly after locking, I can see a (VT) cursor blinking once, then I see the mouse pointer again on a blank scrren for a glimpse, then the screen goes off.

Sadly, there are no plans to change how light-locker works, so this will remain a known limitation.

The Xubuntu devs are currently creating a screen locker for the Xfce project (xfce4-screensaver). It will not rely on VT switching while still offering a nice look and feel. Future Xubuntu and Ubuntu Studio releases will most likely use this new locker instead.
